From: Kevin Darbyshire-Bryant Date: Sun, 6 May 2018 14:20:01 +0000 (+0000) Subject: iproute2: backport json_print-fix-hidden-64-bit-type-promotion X-Git-Tag: v19.07.0-rc1~3810 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ad5af37ca793b8c065d40a10054fd24b88705180;p=openwrt%2Fstaging%2Fhauke.git iproute2: backport json_print-fix-hidden-64-bit-type-promotion The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software. print_uint() will silently promote its variable type to uint64_t, but there is nothing that ensures that the format string specifier passed along with it fits (and the function name suggest to pass "%u"). Fix this by changing print_uint() to use a native 'unsigned int' type, and introduce a separate print_u64() function for printing 64-bit values. All call sites that were actually printing 64-bit values using print_uint() are converted to use print_u64() instead. Since print_int() was already using native int types, just add a print_s64() to match, but don't convert any call sites.
